However, as has been discussed by Caticha in [1]}, as well as, for instance, by Hall and Reginatto [2]} in a slightly different context, this potential can too be derived from symmetry principles. While such approaches greatly improve upon previous heuristic arguments for the quantum potential, such as in [3]}, they have yet to be tested in the regime of relativistic quantum fields, which is our primary focus here. Thus for our purposes we simply include such a potential, as further study into the origin of the quantum potential falls outside the scope of this thesis.
